Patented Feb. 25, 1936 PATE 'i' FEICE CONTAINER FOR LIP STICKS AND THE LIKE 3 Claims.

This invention relates to containers designed primarily for use with lipsticks although it will be apparent that the nature of the element carried therein is immaterial. The principal object of the invention is to provide an improved container having novel mechanism for operating a carrier for the material and opening and closing the container in desired timed relation to the movements of the carrier. The improved mechanism is characterized principally by simplicity, cheapness, compactness and the provision of a maximum travel for the carrier' in a container of minimum dimensions. More particularly, the invention has for its object to provide an actuator for the carrier which shall be movable about a iixed axis, the preferred embodiment taking the form of an operating disk or its equivalent, rotatable within the container to advance and retract the carrier. A further object of the invention is to incorporate 2g in an actuator having the characteristics indicated an operating element so related to the axis of movement of the actuating member that it will impart to the carrier a travel of approximately twice the effective range of movement of the operating element itself. More particularly, this object is obtained by providing a cam surface which is so related to the carrier and to the axis of movement of the actuating member that the carrier will be given a travel of approximately twice the length of the cam itself.

A further object of the invention is to provide a container of circular form in which the carrier and associated mechanism is housed, the container itself being very compact and handy and 35 by means of the improved operating mechanism adapted to carry a pomade stick or the like which may be of a length substantially equal to the diameter of the container and yet be readily expelled from thev container to the desired maxi- 40 mum extent.

A further object of the invention is to associate the closure for the container with the actuating member so that automatic operation is obtained, meaning that the opening through which 454 the pomade is expelled is automatically opened before its movement begins and is subsequently closed after its complete retraction.

The invention will be described more particularly inY connection withthe embodiment shown in the accompanying drawing which is intended to be merely illustrative, and in which:

It will be apparent to one skilled in the art as the description proceeds, that the improved container need not be circular in form nor need the actuating member to be described in connection with the illustrated embodiment comprise a circular disk rotating about a fixed central axis. The same mode of operation in accordance with the novel principles set forth herein can be accomplished in containers of other superiicial form and with actuating members that are not disks. However, it will be apparent that the invention rests on certain principles involving certain relationships between the elements and while the appended claims are ntended to cover equivalent structures embodying such principles they are not intended to cover other structures in which such principles are not to be found.

In the form shown the container proper comprises a back wall a having a circular end wall a' interrupted at a2 to provide an opening through which the pomade b or other element can be expelled. The front wall of the container comprises a plate c which has a circumferential segmental-wall c adapted to be nested within the circular wall a of the container and retained rotatably therein but against axial displacement as by turning over slightly the edge a3 of the circular wall a. Any suitable form of operating linger piece shown as a diametrically extending rib c2 may be carried on the outer face of the plate c to permit convenient rotation thereof in either direction. When the pomade or other material is housed within the container the segmental Wall c will extend across the opening a2 so as to constitute a closure therefor whereas when the pomade is to be expelled, rotation of the plate c will carry the segmental wall c away from the opening and the interrupted portion of this wall is of such circumferential length as to be in registry with the opening a2 during the entire travel of the pomade.

Within the container is mounted a back plate d which in the illustrated embodiment is circular in form to conform to the shape of the back wall a. The plate d may have struck out therefrom segmental flanges d which are bent into parallelism so as to constitute a track in which the carrier e for the pomade is slidably mounted. The plate d, of course, is fixed with respect to the back wall a so that it cannot rotate and and the carrier e is thus required to move in a fixed path.

The carrier e has secured thereto a pin b which is off the center line of the carrier. In the illustrated embodiment the carrier has a laterally extending flange b2 to which this pin is secured. On the rear face of the plate c is secured a disk f. This disk has formed therein an arcuate slot f' which is concentric with the periphery of the disk, that is to say, the arc is struck from the axis of the disk, indicated at f2. When the carrier e is in its fully retracted position the pin b', which is engaged with the slot f', is adjacent one end thereof. Rotation of the disk f through rotation of the plate c by the iinger piece c2 is permitted by reason of the concentric character of the slot f' in which the pin b is disposed. It is to be understood that the disk f is xed relatively to the plate c so as to rotate therewith. In fact, the slot f might be formed directly in the plate c, if desired. The parts are so related that when the carrier is fully retracted as illustrated in Figure 6 the vsegmental circumferential wall c carried by the plate c overlies the opening c2 in the container and closes it. However, when the plate c is rotated through the distance which finds the pin b' riding in the slot f the said circumferential wall c' will be carried away from the opening a2 so that the pomade is free to be expelled therethrough. The slot f' at one end extends radially of the disk f as indicated at f3. The exact form of this portion of the slot is not essential since it may be somewhat curved or may extend along a true radius of the disk. However, it is regarded as important that the portion f3 of the slot shall not extend generally to the left of the axis f2 of the disk as viewed in Figure 4 when the disk, as viewed in Figure 4, is to be rotated in a counterclockwise direction. As viewed from the front of the plate c (Figure l), the slot f3 `should not extend to the right of the axis f2, the plate being rotatable in a clockwise direction, to expel the pomade. Continued rotation, however, of the disk f will carry the pin b' out of the portion f of the slot and bring it into communication with the radially extending portion f3. The outer edge f4 of this portion of the slot may be regarded as a cam surface so far as concerns its action on the pin. When this edge deviates from a line concentric with the axis f2 of rotation of the disk a component of force will be impressed on the pin b in'such direction as to urge the carrier e along its track formed by the flanges d. As the rotation of the disk f continues the operating edge f4 of the slot will move the carrier e forwardly, as viewed in Figure 6. The pin b will reach its closest position to the axis f2 of rotation of the disk at the moment that the pin and said axis lie in a plane at right angles to the axis of movement of the carrier. The portion f3 of the slot is so designed that at that moment the pin b may be located near the inner end of the slot f3. Continued rotation of the disk will exert pressure on the pin b through the edge f4 of the slot still causing the carrier e to continue its outward travel. However, the pin b as viewed with relation to the slot f3 will recede from the end of the slot and travel towards the arcuate portion f. Such relationship is indicated in Figure 7 where the carrier e is shown in such position that the pomade b is fully exposed beyond the side wall of the container. When the plate c is rotated in a counterclockwise direction as viewed in Figure 1 (that is to say, when the disk f as viewed in Figure 4 is rotated in a clockwise direction) theactuating force will be transmitted through the other edge f of the slot f3 to the pin b to move the carrier inwardly, the pin ultimately finding itself opposite to the arcuate slot f when the carrier is fully retracted. At this moment, the interrupted edge of the circumferential Wall c approaches the opening a2.

Continued rotation of the plate c will serve tol bring this segmental wall c over the opening a2 to close the container and the parts will eventually come to rest with the pin b at the end of the slot f as indicated in Figure 6.

From the description given it will be evident that the opening of the container with relation to the actuation of the carrier is so related as to constitute what is commonly termed an automatic action. The edge ,f4 of the lslot f3 which is termed a cam, in that its action on the pin b' is that of a cam, is so disposed in the operating element that it cau-ses the pin to travel rectilinearly a distance substantially twice the length of the cam itself. This is obviously a very desirable condition because it enables the parts to be made very compact and the pomade to be of of a length equal substantially to the diameter of the container. Compactness, simplicity, cheapness and maximum travel for the pomade with relation to the dimensions of the container are primary factors.

I claim as my invention:

l. A container for a lipstick or the like having an opening through which the material is movable, a carrier for the material movable rectilinearly within the container, an'actuating disk rotatable about its central axis, means to rotate the disk, a slot in the disk extending generally radially thereof, a pin mounted on the carrierV offset from the central axis of the carrier and engaging said slot whereby rotary movement of the disk imparts rectilinear movement to the carrier. Y

2. A container for a lipstick or the like having an opening through which the material is movable, a carrier for the material movable rectilinearly within the container, an actuating disk rotatable about its central axis, means to rotate the disk, a slot in the disk extending generally radially thereof, a pin mounted on the carrier oiset from the central axis of the carrier and engaging said slot whereby rotary movement of the disk imparts rectilinear movement to the carrier, the said slot being so disposed with relation to the carrier and the axis of rotation that rotation of the disk causes movement of the carrier for a distance greater than the effective operating length of the slot.

3. A container for a lipstick or the like having an opening through which the material is movable, a carrier for the material movable rectilinearly within the container, an actuating disk rotatable upon a central axis, means to rotate the disk, a slot in the disk extending generally radially thereof, a pin mounted on the carrier oset from the central axis of the carrier and engaging said slot whereby rotary movement of the disk imparts rectilinear movement to the carrier and causes the pin to move in the slot toward the axis of the container and subsequently in the continued motion of the disk causes the pin to move outwardly in the slot.
